Evolution review

Which of the following best supports the scientific theory of evolution?

• fossil evidence

• climate change

• plate tectonics

• rock types

On a farm, Marcia observes that individuals of a certain goat species have slightly different sizes and colors. What characteristic of populations is Marcia observing?

• adaption

• evolution

• selection

• variation

Which refers the process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations?

• adaptation

• mimicry

• natural selection

• selective breeding

Which of the following is a correct statement about the relationship between natural selection and evolution?

• Natural selection results from evolution.

• Natural selection includes evolution as a part of it.

• Natural selection and evolution are the same thing.

• Natural selection is one mechanism of evolution.

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups, that they will never meet in nature again. What type of reproductive barrier is this?

• behavioral isolation
• temporal isolation 
• gametic isolation
• geographic isolation 

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are beginning to only mate with the type of males with the tail they prefer. What type of reproductive barrier is this?

• behavioral isolation
• hybrid sterility 
• temporal isolation
• mechanical isolation 

The flowers of pink tulips open in the morning, while the flowers of lavender tulips open in the early afternoon. The bees that pollinate these tulips cannot carry pollen back & forth between the two types of tulips because of their flowers being closed at different times of day. What type of reproductive barrier is this?

• behavioral isolation
• hybrid sterility 
• temporal isolation
• mechanical isolation 

The term for the formation of new and distinct species over the course of evolution is...

• speciation
• biological species concept
• reproductive barrier
• natural selection

What is a species? 

• A group of organisms that can mate with each other and produce fertile offspring. 
• A group of organisms that can mate and produce offspring even if those offspring are infertile.
• A group of organisms that genetically are very different from each other. 
• Indivual organisms that live in the same environment. 

A new river forms and splits two populations, causing ______________ speciation

• Sympatric

• Allopatric

• Extreme

• Convergent
